This is when you don't have Estimating enabled but have service receivables and inventory enabled.

You are able to add parts in bulk, however, when you open maintain parts database, it doesn't have assign vendors tab. If you exit from maintain parts database window it prompts this error 'Object reference not set to an instance of an object.' then it closes out sage 100 contractor.

In my menu under 9-5, it shows that Maintain Parts Database as available yet it doesn't have full functionality thus crushing sage 100 contractor.

Possible solutions:
Enable Assign vendors tab so that it stops crushing Sage 100?
Could you stop Maintain Parts Database from crushing Sage 100 Contractor although you don't have Estimating enabled?
Provide better error messages that point to not having Estimating module enabled?
